Compare any two graphics cards:
Radeon HD 6950 2GB vs Radeon R9 380 4G
IntroThe Radeon HD 6950 2GB has a core clock speed of 800 MHz and a GDDR5 memory frequency of 1250 MHz. It also features a 256-bit memory bus, and uses a 40 nm design. It features 1408 SPUs, 88 Texture Address Units, and 32 ROPs.Compare those specifications to the Radeon R9 380 4G, which comes with a clock frequency of 970 MHz and a GDDR5 memory frequency of 1425 MHz. It also makes use of a 256-bit memory bus, and uses a 28 nm design. It is made up of 1792 SPUs, 112 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon R9 380 4G should in theory be a small bit better than the Radeon HD 6950 2GB in general. (explain)
Texel RateThe Radeon R9 380 4G should be a lot (more or less 54%) faster with regards to anisotropic filtering than the Radeon HD 6950 2GB. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon R9 380 4G is the winner, by a large margin. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
